Feasibility study of different scenarios of CCHP for a residential complex

Combined Cooling, Heating and Power generation (CCHP) has played an important role in saving the fuels energy in last decades. CCHP plants applying on residential complex can supply large amount of required electrical and thermal energy. In comparison with traditional methods its efficiency is higher, and it can also play an important role to reduce pollution. By combining CCHP methods with Distributed Generation (DG), it's possible to use these systems in big complexes consisting of different kinds of buildings such as residential, commercial, etc. Feasibility study of these systems is necessary for selection and design of CCHP and evaluation of the best method of supplying the demands. In this study, the principal demands of a complex consisting of 433 buildings are initially calculated and then a suitable CCHP plant is proposed and designed. In the next step, by means of a computer code, the hourly results of the simulation are presented for two major strategies of supplying the demand; in the first method, producing the electrical demand is in precedence and in the second, thermal demands is in priority. Eventually by applying the economical analysis, the best strategy will be introduced.
